I have 3 songs that I were not purchased from itunes that are on iTunes 11 on my mac. In the previous iTunes, I could right click and select 'add to icloud' and it would add it to the cloud across my devices (iPhone 4S & iPad 2)
However, the 'add to cloud' option has disappeared (it seems to already be in the cloud), but my ipad is not recognising the new song. It's like I need to tell the ipad to search for new icloud updates or something. With previous iTunes it was almost instant - when a song was loaded on my mac, it appeared on my iPad 2 or iPhone 4s, but now it's not appearing at all - not even greyed out so I can download it.
